To all whom it may concern: I

Be it known that I, osnrn: L. MAoKEY, a citizen of the United States, 'I'6S'1Cl1l1 at Fowler, in the county of Adams and btate of Illinois, have invented "new and useful Improvements in Metallic Grain-Doors for Cars, of which the following is a specification.

The object of my present invention is the provision of a strong and otherwise efiicient metallic grain door for cars, and one that is susceptible of ready ,manipulation and is adapted when in closure service to preclude the leakage of grain through the door opening of a car. a i 3 To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby inade a part thereof:

Figure 1 is an interior elevation illustrating my improved gram door as fully closed and secured in'closed POSltlOIL Fig. 2 is a horizontal section taken in the plane indicated by the line 22 of Fig. 4, looking downwardly. I

Fig. 3 is a horizontal section taken in the plane indicated by the line 33 of Fig. 4, looking downwardly.

Fig. 4 is an elevation showing the outer side of the fully closed door.

Fig. 5 is a vertical transverse'secti'ontaken in the plane indicated by. the line5 5 of Fig. l, looking toward the right.

Fig. 6 is a detail ver'ticaltransverse section, taken in the plane indicated by the line 6-6 of Fig. 4, looking toward the right.

Fig. 7 is an elevation showing the outer side of thecar and the members 'ofthe door, as the same appear when positioned to'leave the door opening entirely unobstructed.

Similar numerals of reference designate corresponding parts ingal-l' of theviews of the drawings.

In furtherance of my invention, the side wall 1 of the car body is provided at opposite sides of the door opening 2 with keepers 3, and the side stiles l of the door opening are also equipped wlth pivoted hooks 5. an opening 7 bridged by a keeper bar 8. On the said 'wall'l of the car body is a supporting hook 9, and connected by a pin 10 to the crown bar 11 of the door frameis a brace bar 12. The said brace bar is slotted at 13 to receive the headed pin 10, andwhen Also in the door sill 6 is provided not in use said brace bar is adaptedto be positioned on the hook 9, as appears in Fig. .7. At its lower end thebrace bar 12'has an angularly disposed terminal portion 14, and

pivoted to the said bar 12 at an intermedi ate point in its length is a-hook 15.

Superimposed upon and fixedly connected to the sill 6 at opposite sides'of the door opening 2 are hinge members 16, and connected by horizontal and transverse pintles 17 to said hinge members 16, are complementaryhnige members 18 that form part of the Specification of Lettersi'atent. 'Patented Oct. 19, 1920.

lower door members 19 and 20, which are I formed of sheet-metal. At their lower edges the door members 19 and 20 have'outwardly disposed horizontal flanges 21 to bear on the sill 6, and at their outer :end edges the said door members haveinwardly directed flanges 22 designed to rest at the outer sldes of the stiles 4, with a view'to' preventing the leakage'of grainat such points.

The free ends of the lower door members 19 and 20 are each inclined slightly from the vertical, as will be'understood by comparison of Figs. 1 and 4. Thelower door Inember 20 is provided at its .outerside with a similarly inclined keeper. flange 24, 'Fig. 4, and the door member 19 is'provided at its inner side witha similarly'inclined keeper flange 23, Fig. 1. The 'doormember 20 is also provided with a-hook 25, Figsl was,

which-is adapted when the door members 19 and 20 arein closed position, to lap -.over and hold the upper free portion of the door member 19 flat against the door-member 20. It will also-be noticed at this point that when the door members 19 and 20 are closed,

the free end of each will be disposed in the; inclined flange of the other, with the result that the door members 19 and.20 will be:

held together and braced eachby the other;

It will also benoticed by reference to Figs -5, that when the bar 12 is in use, the said bar 12 rests at the inner side ofthe door cally swinging metallic door members 27 I and 28 which are also susceptible of being readily swung from the working position shown in Fig. l to the idle position shown in Fig. 7. The member 27 is provided at its inner side with a keeper flange 29 to receive the free end of the member 28, and the member 28 is provided at its outer side with a keeper flange 30 to receive the free end of the member 27.

Hinged at 31 to the upper edges of the intermediate door members 27' and 28 are transversely swinging, lapped door members 82 which constitute the upper portions or members of the doors. It will also be noted here that the door members 27 and 28 as well as the door members 32 are provided at their outer ends with inwardly directed flanges 33, adapted when the members are in working positions to lap the outer sides of the stiles 4.

For the purpose of detachably securing the upper door members 32 in their working position and in that way contribute to the resisting capacity of the door as a whole, I provide the hooks 5 pivoted to the inner sides of the stiles i and adapted to be swung on and off the upper edges of the upper door members 32.

I designate the several door members of my improvement as metallic members, inasmuch as I contemplate inpractice making the said members of appropriate sheetmetal. It is, however, within the purview or" my invention to make the door members of any material compatible with their purpose, and it is to be so understood.

It will be apparent from the foregoing that when the several door members are secured in the positions shown in Fig. 1, they will constitute an eliicient grain door; also, that the upper door members 32 may be swung downwardly against the intermediate members 27 and 28, and then, if desired, the

member 27 with one member 32 thereon may be swung open and into engagement with one of the keepers 3, and the other member 28 with its member 32 may be swung into open position and disposed in the other keeper 3. It will also be understood that the lower members 19 and 20 may be swung to open position and disposed in the keepers 3, after which the brace bar 12 may be manipulated to the position shown in Fig. 7, with the result that the door opening 2 will be left entirely unobstructed.

It follows from the foregoing that the door members 19 and 20 may be used either with or without the intermediate door members 27 and 28, and that when the latter door members 27 and 28 are in use, the upper door members 32 may be secured in working position above the members 27 and 28, ormay be lapped at outer sides of the said members 27 and 28 as conditions require.

In addition to the practical advantages hereinbefor'e ascribed to my novel grain door, it will be appreciated that the door as a whole is strong and durable, and is therefore well adapted to withstand the rough usage to which grain doors are ordinarily subjected.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

A grain door construction comprising the sill, side stiles and crown-bar of a door frame, and the side wall of a car body, said sill having an opening in its upper side and a keeper bar bridging said opening, hooks pivoted to the inner sides of the stiles, keepers carried at the outer sides or" the side wall of the car body, a supporting hook also carried on the outer side of said side wall, a brace bar pivotally and adjustably connected to the crown-bar and having an angularly disposed terminal portion at its free end and also having a pivoted hook at an intermediate point of its length, lower deer members connected through horizontal transversely disposed hinges to the sill and having outwardly directed base flanges and inwardly directed outer end flanges and also having keeper flanges, the keeper flange on each lower member to receive the free end of the other lower member, a hook on one lower member to lap over the upperedge oi the other lower member, intermediate door members hinged to the outer side of the side wall of the body and each having a keeper flange to receive the free end of the other, and each having inwardly directed outer end flanges, and transversely swinging lapped upper door members hinged on the upper edges of the intermediate members andhaving inwardly directed outer end flanges; said upper members being adapted to be engaged and held by the hooks on the stiles.

In testimony whereof I affix my signature.

JOSEPH L. MAOKEY.
